Updating in Play
Painter usually is mostly dormant in Play mode. If you’re concerned about eliminating ALL effects that Painter may have in Play mode, just close the Painter window. When the window is open there are internal events that aren’t intercepted during Play.
If you want to be able to examine the fields of a TilePlus tile during play mode, ensure that Update In Play is active in the Settings panel by clicking its checkbox on (note that this is the default state).
Doing so will allow inspectors to update in Play mode.
Validate Tilemaps in Play appears when Update In Play is checked. Its default state is ON.
Updating inspectors can run into the situation where a Tilemap is deleted in Play mode. This would cause a null reference exception since Painter would still be trying to examine that tile. Hence, when Update in Play is checked, Unity’s Hierarchy Changed callback is used to test for adding/removing Tilemaps.
These tests do take time and if you don’t need these tests, uncheck Validate Tilemaps in Play but be aware that null reference exceptions can occur and cannot be considered an error or bug.
Painter Exclusive Mode
The TilePlus Configuration dialog has a checkbox for “Painter Exclusive” and there’s a corresponding option button at the bottom of the Painter window.
Side note: The convention in the TilePlus system is that a configuration item is in the TilePlus configuration if it at all affects that system even if the configuration item involves Painter.
This option controls certain issues that can occur when both Tile+Painter and the UTE are both open at the same time:
• Both the TilePlus Brush and Painter will try to draw text into the Scene View.
• The UTE can grab focus and/or being the active “Tool” away from Painter when you don’t want it to.
Setting this option ON means that Painter will have exclusive control in the Scene and using the Palette won't switch Editor Tools.
